Important safety notes

G

WARNING

If service work is not carried out correctly, the

operating

safety of your vehicle may be affec-

ted. This could cause you to lose control of

your vehicle and cause an accident. More-

over, the safety systems may no longer be

able to protect you or others as they are

designed to do.

Always have service work carried out at a

qualified specialist workshop.

G

WARNING

Modifications to or work performed incor-

rectly on the following parts can result in the

restraint

systems not functioning as intended:

R

the restraint system, consisting of seat

belts and their anchorage points, belt ten-

sioners, belt force limiters and airbags

R

the wiring

R

networked electronic systems

Airbags and belt tensioners could fail to

deploy or be triggered in an accident despite

the deceleration force being sufficient to trig-

ger the systems, or could be triggered unin-

tentionally. For this reason, never make any

modifications to the restraint systems.

Therefore, you must not tamper with elec-

tronic components or their software.

The seat belts, together with SRS (Supple-

mental Restraint System), are complemen-

tary, co-ordinated restraint systems

(Y page 41). They reduce the risk of injury

in specific, pre-defined types of accident sit-

uations and thereby increase occupant

safety. However, seat belts and airbags gen-

erally do not protect against objects pene-

trating the vehicle from the outside.

To ensure that the restraint systems can

deliver their full potential protection, make

sure that:

R

the seat and head restraint are adjusted

properly

(Y page 92)

R

the seat belt has been fastened properly

(Y page 46)

R

the airbags can inflate unrestricted if

deployed (Y page 42)

R

the steering wheel is adjusted properly

(Y page 98)

R

the restraint systems have not been modi-

fied

An airbag increases the protection of vehicle

occupants wearing a seat belt. However, air-

bags are only an additional restraint system

which complements, but does not replace,

the seat belt. All vehicle occupants must wear

their seat belt correctly at all times, even if

the vehicle is equipped with airbags. The air-

bags are not deployed in all types of acci-

dents. For example, if the protective capacity

of correctly fastened seat belts is not

increased by deploying the airbags, the air-

bags will not deploy.

Airbag deployment only provides increased

protection if the seat belt is worn correctly.

The seat belt helps, firstly, to keep the vehicle

occupant in the best position in relation to the

airbag. Secondly, in a head-on collision, for

example, the seat belt prevents the vehicle

occupant from being propelled towards the

point of impact.
